What is Llasa-8B?
Llasa-8B is an innovative text-to-speech (TTS) system that extends the capabilities of the LLaMA language model by incorporating speech synthesis capabilities. Built on the foundation of LLaMA's 8B parameter architecture, it integrates XCodec2's codebook containing 65,536 speech tokens to enable high-quality speech generation from text input.
Implementation Details
The model leverages a unique approach that treats speech synthesis as a language modeling task by converting audio into single-codebook tokens. This seamless integration with the LLaMA framework allows for traditional LLM training techniques to be applied to TTS tasks. The model can generate speech either directly from text input or by utilizing speech prompts for voice cloning.

- Compatible with existing LLM optimization techniques
- Operates at 16kHz sample rate
Core Capabilities
- Direct text-to-speech synthesis
- Voice cloning with speech prompts
- Complex text comprehension in both Chinese and English
- Handling of sophisticated formatting and punctuation
- Support for mixed-language processing
